Grinding sound with turning, 3.3 GT

[Kazz]

LOL You should feel my modified '03 Evo scrabble on pavement when I turn it sharp and move slowly. You don't have to hear it, you can feel it.

Since installing aftermarket mid-pipes (secondary cat deletes from SSR Performance) I began experiencing a grinding sound while turning. A metal on metal sound. Most noticeable on left turns and seemed to originate from the drivers side. It would usually occur on the first turn or two after start up and then disappear. My AWD 3.3tt was completely quiet prior.

So I took a closer look under the car and noticed that the heat shielding in the tunnel above the driver side pipe was very close to striking the pipe. I was able to loosen and adjust the midpipe to move it down and give it some more clearance. I also used my hands to press the heat shielding up and away from the pipe. It?s very flexible material so bends easily under pressure.

Since doing this I?ve had no noise while turning.

Has anyone who is experiencing this issue on a stock car had the dealer inspect the clearance around the stock midpipes? I could easily see the pipe and heat shielding expanding when warming, causing the grinding. When I removed the stock pipes they were quite tight to the heat shielding.

Just curious about the relationship between grinding when turning and the midpipe shielding. Does this mean that something rotating like the wheel is coming in contact with the exhaust? Or is more related to the exhaust shifting/moving when turning?

I have a RWD GT 3.3 Aussie model and notice a sound/vibration/possible grinding mainly when navigating around car parks or T-junctions etc when turning after being stationary.

No, nothing should be contacting/rubbing other than the exhaust piping on the heat shielding as it expands or shifts with the chassis.

I actually think mine could be related to LSD noise when the car is cold and performing tight turns. My mate was sitting in the rear of the car yesterday and the noise was even more obvious to him.

I’m located in Canada and I have the same noise. It started at 6-months and 3000 km. There was no weird sound when I got the car. It started a week after I put my winter tires. When I put back my new summer tires, the sound was still there. Here is how I can reproduce it.

1-put the car on D and keep the car stopped.
2-Turn the wheels to make a turn (worst if you turn the wheels to the max).
3-I press the gaz pedal to go at parking speed (5-15 km/h)
4-A rubbing sound is easy to ear.
This is happening going to left or right and it’s getting worst from the beginning, last october. My car is now at 9000km.

I’ve got a lot of explanations like the thread of the tires and this is normal from the dealership, but it has nothing to do with the thread as I mentioned earlier.

I had a 2018 Stinger 3.3 awd during 4 years and it never did that sound. We have 2 awd vehicles and they don’t have that sound. It looks like a differential problem. I saw a service in Australia about this, requesting to change the vicosity of the oil, but it is for RWD cars only. All of the dealerships I talked to said there’s nothing wrong, but this sound is very annoying and it looks like something will come apart one day, like a wheel…

I know this thread is old but I still wanna try my luck here:

I think I have the same issue as OP, but I´m not sure. Everytime I steer to the right/left and give my AWD Stinger a lil bit of gas, I can hear some clonking/slipping/skidding/scrubbing//scraping/binding/grinding or whatever you wanna call it. It gets way worse when it´s wet outside. A couple of days ago I wanted to drive off my driveway as the rain was pouring like crazy, but my car only vibrated and/or made one or more of the sounds stated above. It also felt like I wasn´t moving at all or so little that I didn´t notice. I then let off of the gas, because it felt like something is or will break. I then proceeded to reduce the steering ange and gave even less gas than before. The sound and shocks still were noticible through the car, but it was way better. This only happens at slow speeds or from a standstill.

I´m still confused because at one side many people stated that they have the same issue but others state that they never had such isses. So whats true now? Is this normal or not?

I found a video on youtube of a Jaguar XE-F that has the same issue and you can hear it quiete good in it. The Name of the video is: "2017 Jaguar XE-R Sport 35T AWD Scrubbing" if you wanna look it up.

In my opinion that doesn´t feel normal at all. It feels like something is gonna break sooner or later and tbf I don´t even like driving the stinger with this issue. Everytime I hear it, something inside me breaks...
